Users can request FEBio to output a binary dump file. This dump file can be used to restart the analysis from the time point saved in the dump file. The user can restart the analysis either directly from this binary dump file or via a restart input file, which is described in this chapter. See section 2.8.4↑ for more information on how to use the restart feature.
